I recently acquired a Kuster Woodworking Ultra Sand 36” dual head thickness sander. This company has been out of business for quite awhile, I think since the late 80’s. It is a solid machine but the feed conveyor belt had broke on it with the previous owner and he was unable to find a replacement so he was just manually pushing the stock thru. I measured what the belt should be and it is about 36” x 72”, with the length give or take an inch because of available adjustment. Does anyone know of any belts this size or where I could have a custom one made? I haven’t had much luck searching the WWW.

Rubbercal.com is exactly what I wanted, but the minimum pulley diameter recommended for their belts is 3” and my pulleys are 2”. I contacted industrial abrasives and they were happy to make the belt that I needed. They make it out of aluminum oxide backed 100 or 120 grit sandpaper with a butt joint that they state has minimal height difference. We’ll see, they state that they are 7-10 days out from the finished product and shipping. I also order a roll of 4”x25 yards by 120grit sand paper from them too. The custom belt cost was $40. Excited to see it, hopefully it works. I’ll update when I get it.

And it looks like it’ll be a big undertaking to get the belt on. I’ll have to remove all of drums and guide rollers above to get the table off, slide the belt on (hopefuly) and then reassemble.

Works like a champ. I occasionally have to help turn the belt by hand, I could probably tighten up the belt but I’m a little hesitant to put that much tension on it and risk ripping it. I hope this forum helps someone else someday.
